  Early Earth needed considerably less greenhouse gas to stay warm         


Author: Yousuf Khan
Date: Sep 4, 2008 22:56

This is another article related to recent discussions in here about
"Goldilocks Planet", "Gaia model", and Venus models. There's some of the
usual warnings about the current Global Warming fad (yes, it's a fad,
don't even bother to argue about it), but really the majority of the
article is about how special Earth atmosphere really is. Even in the
early days, when the Sun was basically impotent at heating the Earth
sufficiently, the Earth was able to retain whatever heat was sent its way.

One of the arguments about the Gaia model of Earth is that Earth's
atmosphere is capable of stabilizing its heat retention due to the
effects of life changing the properties of the atmosphere to keep the
temperature ideal for the continued existence of life. Some extreme
interpretations of the Gaia model even argue that the Earth itself is
the biggest organism on Earth, and that all of little things like
bacteria, ants, whales, trees, people, etc. are just individual little
cells fulfilling their tasks to keep the Earth alive.

  scientist say

"The explosive vigour of the universe is thus matched with almost
unbelievable accuracy to its gravitating power. The big bang was not
evidently, any old bang, but an explosion of exquisitely arranged
magnitude."
Paul Davies, Superforce: The Search for a Grand Unified Theory of
Nature, 1984, p. 184

“If the rate of expansion one second after the big bang had been
smaller by even one part in a hundred thousand million million, the
universe would have recollapsed before it ever reached its present
size.”

Stephen Hawking, A Brief History Of Time, Bantam Press, London: 1988,
p. 121-125

"…Something else has to be behind things, somehow guiding them. And
that, one might say, is a kind of mathematical proof of divinity."
Guy Marchie, American Science Writer

Company, 1978, p. 598

  ORBITAL MOTION WITHOUT FORCE

BOOK: ONE WITH THE UNIVERSE-
THE MECHANICS OF

by Allen C. Goodrich

OEBITAL MOTION AND THE FORCE OF GRAVITY ILLUSION.
Copyright 1984 - 2008 Allen C. Goodrich

Most of us were too yoiung to remember when we first heard that it was
a force of gravity that kept us on the earth. The force of gravity
between all masses is one of the best known principles or assumed
facts of modern science. There has been no doubt in our minds that
this is true.So, why should I try to tell you that there is no such
thing as a force of gravity. I might rather tell you that there is no
need for a force of gravity to cause orbital motion or for masses to
stay on the earth's surface.

  Why Earth's mantle is solid         


Author: Andrew Usher
Date: Sep 4, 2008 14:53

Every solid save water ice and a few semi-metals is denser than the
liquid of the same composition, and the same temperature and pressure.

This means that a liquid other than water will not exist beneath a
solid of the same composition in a planet. A magma ocean therefore can
only freeze from the bottom up, except for the granitic crust which,
owing to its composition, is lighter than the liquid mantle. The
amount of granitic crust which could exsolve is pretty high, if the
mean composition is that of albite perhaps 20%% of the mantle in the
extreme - but this would not be reached until far below the solidus.

Freezing from the bottom up is a much faster process than freezing
from the top down, as the heat flux from below continues to decrease
(yes, there is convection, but the effective viscosity is much higher
in a solid than a liquid), and therefore should go to completion.

  FIELD, PARTICLES, SPEED OF LIGHT         


Author: Pentcho Valev

Einsteinians, do you see any relation between the following three
texts:

http://www.tu-harburg.de/rzt/rzt/it/Ether.html
Albert Einstein 1920: "The space-time theory and the kinematics of the
special theory of relativity were modelled on the Maxwell-Lorentz
theory of the electromagnetic field."

http://www.perimeterinstitute.ca/pdf/files/975547d7-2d00-433a-b7e3-4a09145525ca....
Albert Einstein 1954: "I consider it entirely possible that physics
cannot be based upon the field concept, that is on continuous
structures. Then nothing will remain of my whole castle in the air,
including the theory of gravitation, but also nothing of the rest of
contemporary physics."

principle. For instance, if it is so obvious, how...

  ENERGY-DEPENDENT SPEED OF LIGHT         


Author: Pentcho Valev
Date: Sep 4, 2008 13:22

Einsteinians, do you see any relation between the following two texts:

http://umdgrb.umd.edu/cosmic/physics%%20overview.htm
"Some quantum gravity theories predict a breakdown of Lorentz
invariance observable as an energy dependent speed of light, c --> c'
= c + E/ alpha ."

http://arxiv.org/PS_cache/arxiv/pdf/0705/0705.4507v1.pdf
Joao Magueijo and John W. Moffat: "The question is then: If Lorentz
invariance is broken, what happens to the speed of light? Given that
Lorentz invariance follows from two postulates -- (1) relativity of
observers in inertial frames of reference and (2) constancy of the
speed of ligh
--it is clear that either or both of those principles
must be violated."

I am searching for Dubhe (alpha UMa) spectra data or plot.
If someone has or knows where it is possible to find them,
please tell me.

Thanks
